Description

Worm adjusting structure of water drill clamp

Technical Field

The utility model belongs to the technical field of water drill processing, and particularly relates to a worm adjusting structure of a water drill clamp.

Background

As mentioned in a water drill fixture with a patent number of CN212170056U, the water drill fixture is applied to water drill processing equipment, and is an important component on a water drill, the water drill fixture structure generally comprises a fixture body, a worm transversely penetrating the fixture, a cover plate is arranged at the bottom of the fixture body, a whole row of ejector pins are pressed down and vertically inserted into the fixture body, the worm drives the ejector pins to rotate around a pin shaft in the fixture body by meshing with pin teeth arranged on the side walls of the ejector pins, and during processing, the fixture fixes blanks such as a natural water drill or an artificial water drill on one hand and drives the blanks to rotate around a central axis of the fixture on the other hand, so that a plurality of angle conversions of the natural water drill or the artificial water drill are realized to process polished surfaces, and the quality of the water drill is mainly from polished surfaces with multiple angles.

However, the length of the worm in the length direction of the water drill clamp is longer, the middle part of the worm is easy to droop due to the action of gravity, and the meshing relationship with the needle teeth on the thimble can be lost, so that the thimble cannot be driven to rotate, and the machining of the water drill is affected.

Disclosure of Invention
